There are many kinds of birds in the world. They vary in size, shape, color, and speed that you’d be amazed by their diversity. If you think you’ve seen enough birds in your life, you haven’t seen anything yet.
According to the American Museum of Natural History, new studies suggest that there are over 18,000 bird species worldwide—roughly double the number as previously estimated. Moreover, most bird watchers and scientists’ checklists estimate that there are between 9,000 and 10,000 species of birds. However, those figures are based on the “biological species idea,” which defines species in terms of which animals may reproduce with one another. But what we don’t know is that there is a hidden avian diversity or birds that looked identical or were thought to interbreed but are actually different species.
One of the best things about birds is that they can be found almost anywhere. And, while many people are unaware of it, they see and hear a wide variety of birds every day as they go about their everyday lives, such as going to work and stopping by for their morning coffee, going out on their morning run, watching their kid’s soccer game, and going out for lunch with their co-workers. You may not notice these fluffy critters, but they’re everywhere—in the yard, on the street, at the park, and, of course, the countryside.
And, here are six types of birds that are common in the cities that have become urbanized:
● Starling (Sturnus vulgaris)
Starlings are sociable and adaptable birds. They gather in tens of thousands and fly to suitable roosts. When large numbers are gathered in a wooded area, the trees can become saturated with bird droppings and perish.
● House sparrow (Passer domesticus)
The House sparrow is a city bird that was introduced to our streets when horse-driven carriages were the only mode of transportation. The sparrows dined on the spilled grain in the streets and lived near the stables, which were abundant throughout the city.
● Town or Feral Pigeon (Columba livia)
The typical town pigeons we see every day are descended from the wild Rock dove found along coastlines, while city birds are descended from domestic pigeons that escaped from medieval dovecotes. They are cliff-nesting species that use ledges and parapets of city structures, in the same way, they’d nest on a cliff ledge.
● Song Thrush
Unlike the starling and house sparrow, these birds’ natural habitat was woodland or hedgerow, but because these countryside habitats have dwindled over time, many birds have sought refuge in our cities. These ‘song birds’ are known to be territorial, which means that each couple of birds need a piece of land to feed themselves and their young.
The kestrel is a raptor that has taken up residence in our cities. It even builds nests atop tall buildings and can be seen soaring over wastelands and allotments hunting for mice and voles, as well as house sparrows to eat.
● House Martin
House martins can be spotted flying through the air between buildings during the summer seasons. They are not territorial, but they do depend on buildings for nesting sites and a good supply of flying insects for food. Withal, there is more about birds that fascinate us: their behaviors, their intelligence, and songs.
